How to design a physically and mentally effortless HMI?
Ergonomics puts the focus of the design on the operator, so the HMI is engineered around the operator’s needs. This will not only improve work quality and efficiency but also the well-being of the operator.
Simply put, an ergonomic design is a user-friendly design.
However, each application is different in its purpose, type of use and frequency of usage.
For example, a machine that is rented out for a day or two to different people needs to be easy to use with a short learning curve. However, a machine that has the same operator for longer periods of time (months or even years) there is more room for training and therefore the interfaces can be more complex.
An ergonomics study plays a key role in a successful HMI design. The study investigates who is the average user of the HMI and what kind of functions it must have to determine the most efficient and comfortable way to operate the machinery. The design often utilizes not only the operator’s hands and feet but also their touch, sight and hearing senses.
We have established these three pillars of consideration for an ergonomic design:
